<p>so if you have changes that require changes to how rustc is run (and have a cargo patch), that's now "automatic"</p>

<blockquote>
<p>Ignoring compatibility concerns, this seems to be the right thing to do and the fix should push LLD support for mingw targets over the finish line (or almost over).</p>
<p>Perhaps the best thing to do here would be to land the patch and collect possible complaints in the next 6-12 weeks.<br>
The patch can be trivially reverted if it breaks something critical, or if we decide to prolong the complaint collection period for more release cycles.</p>
